Patent GB-2141939-A (GB)
Title: Vascular graft and blood supply method
Inventor: POSSIS ZINON C
IPC: A61F/
Filed: 1983-12-08
Abstract: A vascular graft is used to supply blood to one or more coronary artery branches. The vascular graft has an elongated U-shaped tubular body providing a continuous passage for carrying blood from a high pressure blood supply to a blood receiver. One or more openings in the body allow blood to flow into the coronary artery branches. The flow and pressure of the blood in the passage is controlled by a restriction providing a Venturi passage located remote from the inlet end of the tubular body. The restriction is reinforced with an annular sleeve to maintain a desired cross sectional area and length of the Venturi passage. The pressure differential between the blood supply and blood receiver maintains continuous and adequate blood flow at a desired pressure in the body passage and provides a continual supply of blood for the coronary artery branches.

Title: Pipe couplings
Inventor: FELTON GRAHAM
IPC: F16L37/091
Filed: 1985-03-08
Abstract: A toggle ring (7) for a push-in pipe coupling has a frusto-conical portion (8) with teeth (17) integral with one end of a cylindrical portion (14) the other end of which is integral with an inwardly directed annular flange (15), which substantially increases the radial stiffness of the toggle ring so it retains its shape when gripping a pipe (4) inserted in the socket (1). An annular element (10) with a flange (11) forms part of a thin stainless steel end cap (19) having a skirt (22) terminating in an inturned bead (23) engaging a groove (24) in the outside of the socket (1), thus ensuring an overall outside diameter of the coupling appreciably less than with a plastics end cap. The bead (23) also affords added hoop strength to resist radial expansion under pressurisation of the coupling. <IMAGE>

Title: Book binding machine
Inventor: LAWRENCE CHARLES MICHAEL
IPC: B42C9/00
Filed: 1986-04-25
Abstract: A book binding machine which binds books 12 in discrete stages at three consecutive binding stations. As a book arrives at a first station a length of adhesive tape is fed over the end so as to leave a free end 44 overlapping the book. A heated primary iron, mounted on a reciprocating beam 48 common to all three stations, descends onto the end of the book so as to adhere the tape 44 thereto. The book is then passed to the second station (Figure 4A). A second primary iron 42 descends onto the book to clamp it and a heated secondary iron 57 moves downwards past the primary iron 42 so as to fold the severed end of the tape 44 over the edge of the book. Secondary iron 57 is mounted on the beam 48 by means of a resilient strap 58 which biases it laterally towards the primary iron 42. A camming surface 60 on iron 57 allows it to exert pressure on the spine of the book as it descends. At the third station (Figure 4B) a heated tertiary iron 62 moves horizontally under the end of the book folding the remaining overlapping portion of the tape 44 thereunder. The tertiary iron has a chamfered portion 76 which engages a sloping edge 77 on the frame so as to provide vertical support for the book. A third primary iron 43, suspended from the beam 48, presses on the folded tape. A vertical wall portion 74 on the tertiary iron 62 simultaneously presses the tape 44 onto the spine of the book at its bottom edge. <IMAGE>
Patent GB-2314977-A (GB)
Title: Adaptive nulling
Inventor: MURRAY ROBERT JOHN
IPC: H01Q3/26
Filed: 1986-06-30
Abstract: Methods and systems for adaptive nulling of wave signals received with a plurality of N receiving elements, e.g. radio signals received with antennae (ANT 1 -ANT N ), so as to improve the power ratio of a desired component in the signals to one or more undesired components, wherein signals from all the elements but one (ANT 2 -ANT N ) are weighted (W 2 -W N ) and summed with the unweighted signal from the one element (ANT ), correlated with the unweighted signals from all the elements but the one (ANT 2 -ANT N ), and the weights (W 2 -W N ) adjusted so as to tend to reduce the correlations. To take account of amplitude and phase errors in the system and to make the speed of nulling independent of the relative magnitudes of the components, the correlations are measured with N independent sets of values for the weights (W 2 -W N ); optimum values for tie weights can then be calculated from given equations. The specification also discloses a faster method involving the measurement of signal power, and a "boot-strapping" system (Figure 3) for providing improved separation of a desired component and an undesired component using a discriminator comprising a limiter (LIM) followed by a zonal filter (ZF).

Title: Cyclone separator
Inventor: PRENDERGAST GAVAN JAMES JOSEPH
IPC: B04C5/081
Filed: 1985-01-24
Abstract: A cyclone separator (10) having an inlet with inner and outer profiles (84, 82), viewed in section transverse to the separator axis. This location of any particular point on the outer profile (82) is defined by a vector contained in a plane normal to the separator axis, and having its origin at a location (C) where the outer profile meets the adjacent inner circumference (86) of the separator. As the magnitude of the vector (T) increases, an angle (6) between the vector (T) and a tangent (92) to the circumference (C) which passes through location (C) never decreases and never becomes less than zero. The location of any particular point on the inner profile (84) is defined by a vector (U) having its point of origin at a location (E) where the inner profile or at least its projection meets the separator circumference (86). As the magnitude of vector (U) increases, an angle ( zeta ) between vector (U) and a tangent (93) to the circumference (86) which passes through location (E) never decreases and never becomes less than zero, at least for substantial magnitudes of vector (U). Further modification of the separator is the end wall of the separating chamber portion (14) adjacent overflow outlet (25) is formed of curved configuration. A still further modification is where overflow outlet (25) is formed from a duct (27) which extends through the end wall into the separating chamber (14) a short distance. <IMAGE>

Title: Dewatering a web of fibrous material
Inventor: BLUM REINHARD
IPC: D21F3/02
Filed: 1987-12-21
Abstract: A method and apparatus for removing water from a web (1) of fibrous material such as paper in which the web is pressed against a porous sheet material (3), between either an impermeable band (7) and a roll surface (6) or juxtaposed impermeable bands (7<1>, 7<2>) such that the liquid migrates from the web to the sheet material.

Patent GB-2229756-A (GB)
Title: Testing anchoring device
Inventor: CHAMBERS JOHN THOMAS
IPC: E04G23/02
Filed: 1989-03-16
Abstract: An anchoring device, such as a remedial wall tie, has spaced anchorages 5, 15, eg. for engagement in the leaves of a cavity wall, which can be separately tested for security in a hole or holes. The anchorages are at aligned first and second, tubular, members, 1, 2 having an interconnection 13, 14 permitting limited movement between them in the direction of their alignment. The first member 1 is releasably connectable to a testing device for applying loads to that member to test its anchorage 5, and to the second member 2 through the first member and interconnection to test the anchorage 15 of the second member. If the anchorage of the first member is insufficiently secure the interconnection 13, 14 allows that member to move relative to the second member under the testing load, thereby making the unsecurity apparent at the testing device. In one embodiment one anchorage has laterally movable dogs 21, 23 to grip the hole or holes and the other anchorage is secured by synthetic resin, and in another embodiment both anchorages have dogs. <IMAGE>
